They say that they are BT Technical Department - THEY ARE NOT!!!! They are very friendly and want access to your computer. Hang up straightaway. Their sole aim is to get your bank account details so that they can hack your account.

Scammer calling from "Internet Security Desk at Microsoft" warning me that they have noticed that my computer is leaking dangerous information and they wanted to help me fix the problem. Could not tell me where he was from, or what Microsoft office he worked in.
Be sure to waste their time, they hate that. I also like to ask if their mother know what they do for a living...makes the caller crazy!
